Marcele Vermeulen, a graduate from the Department of Plant Sciences, explores possible threats to crop production; contributing to food security in South Africa.
Global food security is currently threatened both by climate change and the low diversity of crops relied on by humankind to feed a growing world population. Marcele Vermeulen, a graduate in the Department of Plant Sciences who will receive her PhD at the December graduation ceremonies at the University of the Free State (UFS), is part of a team that is working hard to add to the diversity of staple foods in South Africa.

In the drive to focus on alternative crops, Marcele is researching the crop, Amaranthus cruentus, (grain amaranth). It is more tolerant to environmental stress for large-scale production, thereby also diversifying staple crops.

Relatively new development

“Amaranthus cruentus is an excellent candidate due to its high nutritional value and tolerance to drought and high temperatures. It can be mixed with conventional maize meal, to increase the protein intake of its consumers,” said Marcele.

The production of A. cruentus as a grain crop in South Africa is a relatively new development.

In her research, exploring the possible threats to crop production and paying particular attention to dominant plant pathogens in the Amaranthus cruentus, Marcele found a correlation between fungal pathogens and insect pests. 

Insect pests can influence plant diseases

Although reports on fungal pathogens and pests specific to A. cruentus are limited to and information for South Africa is limited to this study, there is a possibility that by controlling insect pests such as weevils, one might also be able to control fungal pathogens of Amaranthus cruentus.

Marcele believes that control of weevil pests should thus be the focus of future pest and pathogen management strategies and breeding programmes in A. cruentus.  

“Knowledge gained in my thesis will hopefully aid in the development of future cultivation practices, integrated pest/pathogen management programmes, as well as for the registration of crop protection products for A. cruentus,” Marcele added.

The UFS continues to produce leaders and is proud to have three Mandela Rhodes scholars next year.

Lehlohonolo Mofokeng, Zola Valashiya and Tumelo Morobane all received this prestigious scholarship for 2015.

A Mandela Rhodes Scholarship provides full funding for a maximum of two years of postgraduate study. The award is open to all African citizens under the age of 30 years and recipients must study towards an honours or master’s degree at a recognised South African institution. Although there is no maximum number of awards, the scholarships are highly competitive, with fewer than 30 scholarships being awarded each year since its inception in 2005. The scholarships cover tuition, accommodation, meals, book allowance, general allowance, and travel expenses. Recipients of the Mandela Rhodes Scholarship are students with outstanding academic achievements, who also possess leadership ability, entrepreneurial skills, and a commitment to reconciliation. In addition to receiving funding for their studies, scholars also do a leadership development programme while in residence. The award is named after Nelson Mandela and Cecil Rhodes and is administered by the Mandela Rhodes Foundation, which is a partnership between the Nelson Mandela and the Rhodes Trusts.

Lehlohonolo has just finished his BEd Hons in Philosophy and Policy of Education at the UFS. He hopes to enroll for a master’s degree in Education Policy, Planning and Management at the University of Witwatersrand with his Mandela Rhodes Scholarship.

Zola is originally from Johannesburg and is completing his LLB degree at the UFS this year. He is planning to stay at the UFS in 2015 to do his LLM in Constitutional Law or International Human Rights Law.

Tumelo has a BSc Honours in Actuarial Science and will use this scholarship next year to study towards her master’s degree at the UFS.

“I chose to stay at the UFS because I am doing a great master's project with Munich Re through the UFS,” says Tumelo. 

“Furthermore, the CEO of the Mandela Foundation, Mr Sello Hatang, asked me to work with the foundation on a few projects that mostly focus on keeping the girl child in school across Africa, as well as helping with providing training and workshops on entrepreneurship to young people.

“So, I am looking forward to a very busy year ahead of me, which will be filled with so much learning, growth and making a difference,” Tumelo says.
